They are more delicate then other gourami's (not as delicate as Chocolate gourami's however). Softer water is prefered, with not too much current. They enjoy places to hide in plants, and will not like to be terrorized by other fish (they are very small and easily bullied).

Since these fish are Wild Caught you will want to quarantine them for a while before introducing them into your main tank. They may not eat right away either, so you should find out from your vendor what they were feeding them before you recieved them. It may take a few weeks to get them on a regular feeding schedule (wild caught fish often dont recognize flaked and pelleted foods as food).
